The following notes were taken from the Tuesday, November 10, 2026 Simulator User Group (SUG) meeting. These notes form a summary of the items discussed, and are not intended to be a full transcript. A video of the meeting by Pantera is embedded at the end of this summary – my thanks to her for providing it.
Meeting Overview
- The Simulator User Group (also referred to by its older name of Server User Group) exists to provide an opportunity for discussion about simulator technology, bugs, and feature ideas is held every other Tuesday at 12:00 noon, SLT (holidays, etc., allowing), per the Second Life Public Calendar.
- The “Leviathan Office Hour” meetings are held on the Tuesdays which do not have a formal SUG meeting, and are chaired by Leviathan Linden. They are more brainstorming / general discussion sessions.
- Meetings are held in text in-world, at this location.
Simulator Deployments
- On Tuesday, November 10, the Olive simulator update was be deployed to the SLS Main channel, making it grid-wide. This update includes:
- Pepper Linden’s region crossing code improvements for vehicles – feedback on experiences with the new code is requested here. He also indicated more work is to come on crossings.
- The new Group Role ability to define who in a Group can post URL links to Group Chats (requires viewer support).
- Support for the feature flag required by viewers to be able to safely send the GameControlData UDP message for the new Game_Control capability. Currently, the upcoming viewer 26.5, (in RC/beta at the time of writing), supports Game_Control capabilities, the sending of GameControlData currently must be enabled via Preferences. This will change as Olive moves to being grid-wide.
- Wednesday November 11 should see the RC channels restarted without any updates. The Lua channel servers will also be updating – but this will not be the update with the changes that will case script breakages.
- The (theoretically final) simulator update for 2026 – codenamed Plum – is currently in development.
- This will include a crash fix for a rare simulator crash, and Rider Linden is hoping to get the restrictions lifted in on accept and content types for HTTP, with Rider noting there will be constants that let you indicate that the payloads (the body of the request or response in an http call) should be treated as base64 encoded so they can be brought in and out of scripts, which he hopes to include.
- Leviathan Linden also indicated a number of further crash fixes lined-up for Plum, including one for a big memory leak.
General Team Updates
- Leviathan Linden has been working on simulator crash fixes per above, and also “on some things to try to help game-control viewer get out”, although he also indicated he fell down a few rabbit holes on this and got side-tracked as a result.
- Roxie Linden indicated there:
- Are a few stability fixes going into the voice server which, once implemented, with result in fewer viewer service restarts.
- Has been “good progress” in evaluating transcription technologies, and LL is now looking into what it would look like as far as where it is deployed, how it can be used, etc.
- When asked why transcription isn’t simply viewer / client-side, Roxie noted that there are some security implications, and LL do not want people using their transcription mechanism for non-Second Life purposes, etc. Also, performance can be better optimised if transcription / translation is on the server.
- Later in the meeting, the question of Voice instability at distances from the speaker was raised. While it is hoped the stability improvements mentioned above might fix this issue, but a bug report was requested on the issue.
- Also later in the meeting, Roxie indicated she would like to add more control over attenuation (distance, drop-off, etc.) as well as effects like reverb, echo, EQ, etc; however, it is a matter of getting that work scheduled and designed.
- Pepper Linden has been working to fix a grief mode related to conference chats. This is currently in QA and they are hopeful the fix will be in the Plum simulator update.
- Kyle Linden reiterated his new from the week #45 CCUG that the SL Wiki update is complete, bringing a new default theme, more moderation tools and brings it one stop closer to re-opening contributor access to all registered SL accounts – those who have already volunteered to help moderate should keep an eye out for further communications about helping.
- Harold Linden (Lua):
- Noted that good progress is being made on the Lua front and thanked all those who have submitted bug reports and contributions.
- Indicated that some of the performance analysis pieces which need to be in place before upgrading the SLua VM are in the works by other teams within LL.
- The above are what is holding-up the deployment of the Lua updates liable to cause script breakages. As such, this update might surface prior to Christmas 2026 or in early 2027.
- Overall, if things continue on track grid-wide deployment of Lua should be some time in the first quarter of 2027.
- Documentation for Lua now forms part of the SL Wiki work.
General Discussion
- A discussion on extending PRIM_POINT_LIGHT radius in llSetPrimitiveParams(), pre this Feature Request, which was seen as relatively easy to do from a simulator point-of-view but a) would require viewer work; b) is more a question for either the Content Creation User Group or the Open source Development Group meeting.
- Further discussion on Lua testing (which should be more informative when the “breakage” update has been deployed), and on documentation.
- It was asked when “Combat 2.1” might start as a project – whilst Rider linden would like to get back to the Combat system work as he ideas for friend fire, teams, better respawning, etc., it need time to be allocated as an actual project.
- A user discussion on allowing land to be “vertically parcelled” (so to speak) to allow apartment building in which people can have their own privacy, steaming etc. Something that sounds easy to express but much harder to implement.
- More mention of the emerging vibe-coded viewers starting to appear (Geenz indicated that LL is reviewing its TPV policy requirement in light of these).
- A passing discussion on “void” regions: essentially temporary water region which would spin-up and allow air / water crossing between areas of SL not actually connected by any form of region bridge. Currently, there are no plans to implement this idea.
Date of Next Meetings
- Leviathan Linden: Tuesday, November 17, 2026.
- Formal SUG meeting: Tuesday, November 24, 2026.
